| 20110104628 | GLASS MELTING FURNACE - The present invention relates to a glass meting furnace comprising a channel-shaped melting tank, the batch materials being introduced at an upstream end, the molten glass being recovered at the downstream end, said furnace being heated by means of burners, in which the combustion energy is produced by oxy-fuel combustion in respect of at least 65% thereof, the burners being distributed on the walls along the length of the furnace, in which flue gas discharge is mostly localized close to the upstream end near the openings through which the batch materials are introduced, the rest of the flue gas being removed close to the downstream part so as to maintain dynamic sealing with respect to the surrounding atmosphere. | 05-05-2011 |
| 20120115099 | Calciner Gas Distribution Plate Bypass Mechanism - A calciner includes a calciner gas distribution plate bypass mechanism. The gas distribution plate bypass mechanism is sized and configured to permit gas to enter a calciner at a temperature below a sticky point of material to be calcined and prevent or substantially reduce material buildup on the gas distribution plate. For instance, additional gas may be introduced into the calciner at a position downstream from the gas distribution plate so that additional gas may be fed into the calciner without passing through the gas distribution plate. The additional mass of gas may allow for increased capacity without elevating the temperature of the gas passing through the gas distribution plate or adjacent to the gas distribution plate and provide sufficient heat for calcining the material. A control damper may be utilized in some embodiments to ensure that certain conditions and operating parameters of the calciner are monitored and maintained. | 05-10-2012 |

| 20140045133 | METHOD AND SYSTEM FOR IMPROVING SPATIAL EFFICIENCY OF A FURNACE SYSTEM - A furnace system includes at least one lower radiant section having a first firebox disposed therein and at least one upper radiant section disposed above the at least one lower radiant section. The at least one upper radiant section has a second firebox disposed therein. The furnace system further includes at least one convection section disposed above the at least one upper radiant section and an exhaust corridor defined by the first firebox, the second firebox, and the at least one convection section. Arrangement of the at least one upper radiant section above the at least one lower radiant section reduces an area required for construction of the furnace system. | 02-13-2014 |

| 20080286708 | PROCESS AND SYSTEM EMPLOYING GENERATION OF CONTROLLED FURNACE ATMOSPHERES WITHOUT THE USE OF SEPARATE GAS SUPPLIES OR STAND-ALONE ATMOSPHERE GENERATORS - In a system for processing metal, a furnace is provided which receives the metal being processed. At least one heating burner is provided in the furnace together with at least one atmosphere burner of substantially a same construction as the heating burner. An exhaust of the atmosphere burner at least partially provides an atmosphere within the furnace for the metal processing. An exhaust of the heating burner is separate from the exhaust of the atmosphere burner. A fuel feed for the atmosphere burner and a fuel feed for the heating burner are each separately controllable. | 11-20-2008 |
